Abstract

Se describen composiciones para ajustar el pH del agua de mar para que sean utiles en los procesos de flotacion de metales, al igual que los metodos que utilizan tales composiciones. La precipitacion de sales de magnesio insolubles interfiere con el ajuste del pH del agua de mar cuando se utilizan fuentes convencionales de CaO y/o Ca(OH)2; sin embargo, la adicion de particulas no reactivas (como materiales de desecho de procesos industriales) permite el uso de fuentes de baja calidad de CaO / Ca(OH)2 y reduce el consumo de CaO / Ca(OH)2 de alta calidad para este proposito.Compositions for adjusting the pH of seawater to be useful in metal flotation processes are described, as are methods using such compositions. The precipitation of insoluble magnesium salts interferes with the adjustment of the pH of the seawater when using conventional sources of CaO and / or Ca (OH) 2; However, the addition of non-reactive particles (such as waste materials from industrial processes) allows the use of low-quality sources of CaO / Ca (OH) 2 and reduces the consumption of high-quality CaO / Ca (OH) 2 for this purpose.
